Claims. (01. its-'72) This invention relates to window constructions, and more particularly to an improved metal construction for auxiliary or so-called storm windows and which preferably includes a screen so that the construction has year round utility.

One of the objects of my invention is to provide an auxiliary window construction in which the frame parts are of such design that they may be readily rolled or formed from sheet metal into strips of appropriate cross section and supplied to the trade, either in pieces cut to length for use with standard size windows, or in long strips from which pieces may be cut for windows of other than standard size. This enables the manufacturer to supply dealers or distributors with all the parts (excepting glass panes and screen) that are required for standard size windows, suitably packaged in compact knockdown condition, to be assembled by the dealers or distributors to include glass panes of the correct size instance, the only equipment necessary in such case being a suitable saw. This method of handling avoids shipment of glass with attendant danger of breakage, and saves much space in transportation and storage.

Another object of the invention is to provide an auxiliary window construction that is relatively simple, that is very neat and attractive in appearance, and which is especially convenient A further object of myinvention is to provide an auxiliary window construction, wherein'the sashes are yieldingly retained within the frame.

for easy sliding movement but firmly enough to avoid rattling and-for convenient removal from the frame when occasion requires or when such removal isdesirable. By reason of the neat appearance and compact character of my improved auxiliary window construction, the glass and screen sashes may be left in the window frame the year round without objection.

in detail by reference to the accompanying drawings wherein like reference characters designate like parts throughout the several views.

In the drawings, Fig. 1 represents a front eleva tion of my improved auxiliary window construc-:

of assembly and installation, the members of the window frame requiring no joining together, but being held in proper relation to each other when fitted within and secured to the top and sides of the window in which the frame is to be installed, and which I shall refer to herein as the base window. I

Another object of my invention is to provide top and side members for the window frame,

each of which is rolled or formed from a single strip of sheet metal into a cross section that affords channels for the sash and an outside tion installed in a base window and as viewed. from the outside, with'parts broken away; Fig. I

The top member of myimproved auxiliary window construction is designated, generally, by

the reference numeral I; the right hand side a member, as the parts are viewed inFigs; 1,2 and 6, by the reference numeral 2, while 3 denotes the left hand side member, and A. the bottom member or sill.

In all other respects, 3 is the same as members l and 2.

The reason for the difmember side members I and 2, respectively, being des- .said pressure strips, as by having their middle fillers I1; and, as best appears from Fig. 9, the upper ends of the pressure strips are suitably formed to provide tongues 2! that loosely fit within the lower ends of the channels that con stitute the fillers l1. This arrangement is clearly illustrated in Fig. 8. The pressure strips extend' 'from' the fillers ii to the lower e'nd'of the member 2 andrestupon'the sill w of the base window. A suitable number of bowed leaf springs 2'2 are attached, about midway of their ends, to

This member consists of a relatively deep channel and, as best shown in Fig. '7, it includes front and rear walls '25 and 25, respectively, and a top wall 2'6. This wall is stepped up from the plane it 00-.

cupies inthe zones of the channels i, I and 8, 8 to. a somewhat higher plane in the zone of the channels 9, 9?; thereby to provide a vertical shoulder 28, The member 4 is constructed of suitable sheet-metal, preferably 7 aluminum, and

Where the rear wall joins the top wall, the metal is crimpcd to provide an upstanding bead 29. The

front wall--25 is of a length to fit snugly between the-front flanges of the members 2 and 3, while the rear wall and bead 29' are long enough to of-fr'ame'tniembers I', 2 an'd13 are formed along th'eir ed ges withintil'rned 'lipsfi 'that bearZdi-r' rectIy against the front. surface. of. the frame of the-basecwindow; and said flanges, beingresil-r ientfyieldto any irregularitiesxor difierencesyin dimension of various 'base windows so that in all cases a .neat and attractiveinstallationjs as:

Accordingly the left hand end of the member or sill 4 isheld firmly againstfore-and-aft movement, while the right hand end of said member or. sill is held against such movement by the rear walls of the channels 9, 9 and by the stop 24, the rear end of the latter being closely adjacent the rear- Wall 26 of said member. To sustain-the front wall of the member 4 from being sprung in wardly, the stop 24 maybe of a length substantiallyequal to the normal distance between. the

. front and rear Walls of said member.

The above described frame is equipped with three sashes, two of which are fitted with panes of glass or other transparent material, and across the third of which is stretched a sheet of screen material. In certain of the appended claims, the 1 term panel is used to designate either a pane,

It will also be obor a sheet of screen material, or in plural to des'- ignate both.

The two sashes that carry the panes are of identical construction,'the one toward the.out-, side of the window being designated generally by thereference numeral 30, and the other or intermediate sash by the numeral 3|. .32 denotes,

generally,'the screen sash. Each'of the'sashes -and 3| is' made up of ton-bottom and side members 35, 36 and '31, respectively. All of these -members'are identical in cross section, being tu the sash member 36 is forced over the lower edge of the pane 40 until the mitered ends of the members 36 and 31 meet,-whereupon the bolts are released and are projected by the spring 52 through the aperture 51.

- The frame members 60 of the screen sash 32 are formed to the crosssection shown in Figs. 2

bular and formed from aluminum or other suit-E j able material, to the cross section shown in Figs.

2, -5 and 12-50 as to provide along their inner edges grooves 39.

In- .the fabrication of either of the sashes 30 or 3l,';aip'ane 40 of glass or. other transparent ma teri'al is cut to proper size. The sash members 35, 36 and 31 are then applied to the four'edges of-the :pfane 40 in some. such manner as I shall now describe. Starting, for instance, withthe sashfmember 35, a strip of suitable packing or sealing material is either applied to the edge .of

the pane or to the walls of the groove 39 of the sash member, and said member is then forced over the edge of the pane with said edge tightly.

fitting within the groove. Next, one of v the and 5 to provide a laterally opening groove 6|. A sheet 62 of screen material is stretched across the sash frame and its edge portions are crimped into the grooves 3i and are held therein by forcing into said groove, within the crimped portion of the screen material, rod like retaining elements, 63, which are shown as circular in cross section and they are preferably made of plastic.

, The frame of the screen sash is-assembled insubstantially the same manner as the frames of the other sashes,,and they incorporate in their lower corners the bolts 45.

Each sash is inserted engaging one of its lateral edges in the appropribranches 42 of an L-shaped fitting 43 (Figs. l0, l1

and 1 2) is forced into each end of the sash member with the other branch 42 of said fitting projecting along one of the lateral edges of the pane. Now, the side members 31 are forced over the lateral edges of the pane and, at the same time, {moved along said edges so as to. project their ends over the remaining branches of the aforesaid fittings 43 until the mitered ends of the side members engage the complementary shapedends of the top member. I

According to the present embodimentof the invention, each lower corner of each sash is equipped with a bolt 45. As shownin Figs. i0, 11 and 12, the bolt is provided with a finger piece 46'thatislconnected tosaid bolt by a neck41.

Preferably, t'he bolt, finger piece and neck are integral parts .of a unit which may be die cast or otherwise produced, andthe boltghas, on its inner i ,si de, a groove 48. The angle fittings. 43 are-provided with intersecting grooves 50jand 5| that' are parallel with the branches 42. While these grooves are unnecessary in the fittings that are incorporated in the upper corner of the sash,

for the sake of economy and to simplify assernbly, fittings of the same design are vused in all corners; 'With respect to the fittings thatare to y be incorporated in the lower corners of the sash,

U-shaped wire springs 52 (Fig. '12) are inserted in thevertic'al' slots 5| thereof, one end of the spring being hooked laterally and engaged in a notch 53 of the'fitting, while the other end of the spring projects into the horizontal slot 50. The bolt 45 is next placed within the slot 50 with the last mentioned end of the spring 52 occupying the groove 48 of the bolt. In preparing the members 36 and 31 for incorporation in thesash,

slots 55' and 56 are made in their inside walls. and'in 'the horizontal plane of the slot 56of' each side member 31, an aperture 51 is made in ate channel of the side member 2 against the pressure strip '20. The sash is now thrust laterally so as to compress the springs. 22 enough to permit the opposite edge of the sash to be swung into the plane 'of the corresponding channel of the opposite side member of the frame. Now,, by releasing lateral pressure on the sash, it will be forced in a direction to engage its other lateral edge in the channel of the frame member 3. The sash, thus positioned centrally in the frame, may be slid up'and. down, its edge adjacent the pressure strip ,20 and .filler i1 riding smoothly over both. Each sash, however, is adapted to be held in fully elevated position, fully lowered position, or in an intermediate positionor positions, by engagement of its bolts 45 withinfsuitably located recesses or slots in the bottom wall of the corresponding channel of the frame member 3, and in the web of the pressure strip 2i! wherewiththesash, is engaged. A slot of one of the pressure strips is designated 20 in Fig. 8.

Normally, in cold weather, the sashes occupy the positions in which they are shown in the drawings, the outer sash 30 and screen sash 32 being in fully elevated position and the intermediate sash 3i in lowered or closed position. In such positiomthe lower-rear edge portion of the sash 3| bears against the shoulder 28 of the bottom member or sill 4, so as to effectively close the joint between'said sash and sill, and in order to close the spaces between the lower edge of the outer sash 30 and the topof the intermediate sash 3|,.-when the sashes are in the positions aforesaid, a resilient sealing strip is provided. This strip is preferably made of very thin resilient rust-proof metal. It is formed to the cross section shown in Fig. 5, and is interlocked, with the adjacent edge portion of the pane 40,

within the groove of the member 36 of sash 30.

A similar sealing strip is attached to the inner side of the member 36 of sash 3| so as to close the space between said member and the top member of. the screen sash 32 when, as during the summer, the intermediate'sash 3| is up and, the screen sash is down.

For ventilating purposes, either the intermediate sash 3| may be raised, or the outer sash may be lowered, and held in fully open or partially opened position by the engagement of the bolts 45 with the appropriate ones of the aforesaid slots or recesses. When it is desired to use the screen, both of the sashes 30 and 3| are left into the frame by first sa'sh 'in "the"windovvffr"ame during the Winter, it maybe readily disengaged 'fromthe frame 3 in the manner already described, again needed.
